Bilateral impaired parotid secretory function is mainly related to mumps, which is mainly treated by medication, and the therapeutic effect varies from person to person. 1. Mumps is an acute, self-limiting respiratory disease caused by parotid virus infection. Typical symptoms are localized pain, swelling, and fever, which can also lead to impairment of the normal secretory function of the parotid gland. Mumps can also be caused by bacterial infections leading to suppurative parotitis. 2. Common therapeutic drugs include antiviral drugs such as ribavirin, antibiotics such as penicillin and cephalosporins, and adrenocorticotropic hormones such as dexamethasone. Daily attention should be paid to isolation and prevention of complications such as high fever and recurrent vomiting. If the parotid secretion function is found to be impaired, timely medical treatment should be sought, and unauthorized medication should not be used to avoid delaying the condition. Pay attention to oral hygiene and care, eat less spicy food, quit smoking and drinking, and maintain a regular routine.
